Description

Subscriber Data Management Method of ATM VC Switch

The present invention relates to an ATM VC switch, and in a conventional voice switch or narrow bandwidth integrated service digital network (N-ISDN) switch, each terminal is directly connected one-to-one by a link between the switch and the switch. Only one subscriber could be created on a link.

Therefore, the subscriber creation, modification, deletion, and output command execution among the operating commands operated by the exchange operator were also implemented to be symmetrically handled by the subscriber number and link of the terminal.

However, in order to enhance the multiplexing effect of traffic on a call unlike the voice exchange or the N-ISDN exchange, the ATM VC switch is required to have a plurality of terminals connected to a link physically connected to the switch so that a plurality of calls can be processed.

Therefore, the ATM VC exchange cannot manage subscriber data so that subscriber numbers correspond one-to-one with the corresponding link as in the existing N-ISDN or voice exchange, and the function of the operation command must be changed so that multiple subscribers can be connected to one link. did.

Therefore, it is absolutely necessary to manage data that can create multiple subscribers on one link, change, delete, and print them according to the characteristics of ATM switch, and output all subscriber defenses belonging to the link. .

In order to achieve the above object, the present invention, when the calling subscriber transmits a call setup message to the exchange, the exchange checks whether the calling subscriber is prohibited from calling, and if the calling is prohibited, the call is released immediately. Attorneys should verify that the calling party's call coverage is within the calling party's call tolerance.

Thus, if the call is allowed to be exceeded, the call is released and if it is within the call allowance, the call proceeds continuously.

As described above, the subscriber data is information for determining whether or not the requested call is in progress.

Therefore, in order for the subscriber to set up the call normally, the subscriber data must be stored in the exchange before transmitting the call setup signal.

The contents of the subscriber data are information on the call tolerance of the calling subscriber, that is, group calls, internal calls, and relay calls, international calls, and information indicating whether the subscriber's call is suspended. The subscriber type information indicating whether the subscriber has the personal information or the number included in the group, and the representative number information in the case of the number included in the group, indicating the category of the subscriber. It includes the general subscriber, the priority subscriber, the operator, the information under the data, and the billing form information of the subscriber. Therefore, in order to store such subscriber data in an exchange, an operation command that allows an operator to operate subscriber data is absolutely necessary. In particular, in ATM VC exchanges, multiple subscribers can be created on one link instead of just one to increase the traffic multiplexing effect. Therefore, subscriber data can be operated to easily distinguish and manage all subscribers connected to one link. Command is required. Thus, the operation command for operating the subscriber is a command for creating a new subscriber, and Phil Yong; Accordingly, a command for changing information of subscriber data, a command for deleting unnecessary subscriber data, a command for outputting information possessed by subscriber data, and all subscriber numbers belonging to a subscriber module or link to which the subscriber is connected There is a need for an ATM VC switch subscriber data management function consisting of instructions.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. 1 is a structural diagram of an ATM VC exchange system applied to the present invention. The ATM VC switch is composed of an ATM Local Switching Subsystem (ALS) 300 and an ATM Central Switching Subsystem (ACS) 200.

The local switching subsystem 300 is an interface module that performs a subscriber matching function with a call and connection control processor (CCCP) 300 that performs a call processing function and a subscriber data processing function. The central switching subsystem 200 comprises an operator matching function that provides an interface between an operator terminal and an ATM VC switch, a number translation data processing function, and operation maintenance, maintenance, and billing, and statistics. It is composed of a processor (Operation and Maintenance Processor, OPM) 210.

Looking at the functions of the blocks required to perform the subscriber data, the human machine interface and delivery function (HANDF) 210a analyzes operator commands input from the operator terminal and checks whether they are input according to the command format. If there is no error, it executes the function to request processing as a block to execute this command and outputs the result of completing the input command to the operator terminal.

The user data handling function (UDHF) 310a receives a subscriber number output request from a subscriber generation function, a deletion function, a change function, an information output function, and the human-machine interface transfer function 210a. And a subscriber number output function, and a number data control function (NDCF) 210b performs a number translation data processing function. The number translation associated with subscriber data is generated whenever a subscriber is created, deleted, or changed. Create, delete, and change data, create and delete subscribers from human-machine interface transfer function 210a, analyze the function of receiving and modifying information output requests, and analyzing subscriber numbers, and present users in the relevant call processing processor. The data processing function 310a performs a function for requesting processing of the corresponding function.

In addition, the ALS maintenance library function (LIBMLF) 310b performs a function of checking whether the link with the subscriber module to which the subscriber belongs is normal or abnormal when generating or changing the subscriber data.

2 is a block diagram illustrating the configuration and message flow between the subscriber and the related blocks for performing data management functions implemented on the ATM VC switch according to the present invention.

When the operator enters a subscriber creation, deletion and modification, information output and subscriber number output command at the terminal, the human machine interface transfer function (HANDF) 210a determines whether the commands have been entered as originally defined. If there is no error by checking, it sends the processing request to the number data control function (NDCF) 210b for the subscriber creation, deletion, change, and information output command with the parameter value listed with the corresponding command, and outputs the subscriber number. The command transmits a processing request to the user data processing function (UDHF) 310a.

When the number data control function 201b receives a subscriber generation, deletion, change, and information output command processing request from the human machine interface transfer function (HANDF) 210a, the number data control function 201b processes as follows for each command.

First, for the subscriber generation instruction processing request, the user data in the call processor number among the input parameter information of the subscriber generation instruction consisting of the subscriber number, the call processor number to which the subscriber number is to be generated, the interface module number, and the link number. A subscriber generation request is made with the parameter information input to the processing function (UDHF) 310a.

When the user data processing function receives the subscriber generation request, it first checks whether there is an error in the information values input for subscriber generation.

If there is no error after the inspection, it is determined whether the interface module to create a subscriber is a subscriber interface module or a trunk interface module. If the subscriber interface module is a subscriber interface module, the interface module number inputted to the Library Maintennce ALS Function (LIBMLF) 310a; It asks whether the subscriber number can be generated in the link number.

The ALS preservation library function 310b transmits the result of whether the interface module number and the link number requested by the user data processing function 310a are available to the user data processing function through the switch system shape information.

The user data processing function requests the subscriber number generation to the number data control function (Nunber Data Control, Function, NDCF) 210b if the result received from the ALS maintenance library function is that the corresponding interface module and link are available. .

The number data control function stores the subscriber number and the call processor number to which the subscriber number and the subscriber number belong, the interface module number, and the link number in a number translation relation that manages the subscriber number requested by the user data processing function. .

When the process is completed normally, the number data control function 210b transmits the result of generating the subscriber number to the user data processing function 310a.

The user data processing function receiving the subscriber number generation result adds the subscriber number and subscriber information related to the subscriber number to the subscriber information relation, and then transmits the subscriber generation completion result to the human machine interface transfer function 210a, and the human The machine interface transfer function outputs the subscriber creation completion result to the operator terminal.

Next, the number data control function includes a subscriber deletion command consisting of a subscriber number, a subscriber information output command and a subscriber number, a subscriber number, a call tolerance of the calling subscriber, whether the subscriber is stopped, and the subscriber type, and a representative. Upon receipt of a subscriber change instruction consisting of a number, information of the subscriber's category and the subscriber's billing type, the number data control function searches for a number translation relation with the subscriber's number to find the call processing processor for which the subscriber has been created.

A subscriber deletion, information output and a change request are made together with the parameter information input from the user data processing function in the call processing processor found after the above.

When the user data processing function 310a receives the subscriber deletion request, the user data processing function 310a searches for the existence of the subscriber information relation, and if so, requests the subscriber number deletion to the number data control function 210b.

The number data control function notifies the deletion completion result to the user data processing function after deleting the corresponding subscriber number from the translation relation.

The user data processing function receiving the deletion completion result from the number data control function deletes the corresponding subscriber information from the subscriber information relation and then transmits the subscriber deletion result to the human machine interface transfer function. Outputs to the operator's terminal.

Next, when the user data control function 310a receives the subscriber change request, the user data control function 310a searches whether the corresponding subscriber exists in the subscriber information relation and, if present, the interface modulus number and the link number among the parameter information input to the number data control function 210b. Requires a change of

The number data control function changes the subscriber module number and link number to which the corresponding subscriber number belongs in the number translation relation and transmits the changed result to the user data processing function 310a.

The user data processing function changes the information of the corresponding subscriber in the subscriber information relation according to the input parameter information.

After the change, the user data processing function transmits the result of changing the subscriber information to the human machine interface transfer function 210a, and the human machine interface transfer function outputs the subscriber information change result to the operator terminal.

After the user data processing function 310a receives the subscriber information output request, the user data processing function 310a finds the subscriber information of the corresponding subscriber in the subscriber low-op relation and transmits the subscriber information output result to the human machine interface transfer function 210a and delivers the human machine interface. The function outputs subscriber information to the operator terminal.

Finally, when an operator inputs a subscriber number output command consisting of a call processor number, an interface module number, and a link number from an operator terminal, the human machine interface transfer function 210a determines whether the commands are input as originally defined. If there is no error, the processor transmits a processing request to the user data processing function 310a existing in the input call processing processor with the information of the parameter input together with the corresponding command.

The user data processing function searches the subscriber relation with the interface module number and the link number, finds all the subscriber numbers existing in the corresponding interface module change and the link number, and sorts them in ascending order to transfer the sorted subscriber numbers to the human machine interface. Transmit to 210a.

After transmitting (S12) and receiving an error result (S13), the user data processing function (UDHF) outputs the error result to the operator terminal (S14).

If the result is possible, information to be added to the number translation relation such as subscriber number, call processing processor number, interface module number, and link number information is transmitted to the number data control function (NDCF) (S23).

The number data control function adds the information received from the user data processing function (UDHF) (S24) to the number translation relation (S25) and transmits the added result to the user data processing function (UDHF) (S26).

The user data processing function receiving the subscriber number addition result from the number data control function (S27) determines whether the result is an error (SS28) and if it is an error, transmits the error result to the human machine interface transfer function (HANDF) ( S12) Upon receiving the error result (S13), the human machine interface transfer function HANDF outputs the error result to the operator terminal (S14).

If the result is not an error, subscriber generation information is added to the subscriber information relation (S29). The subscriber generation result is transmitted to the human machine interface transfer function HANDF (S30), and the human machine interface transfer function receiving the subscriber generation result (S31) outputs the result to the operator terminal (S32). Next, when the number data control function receives the subscriber delete instruction processing request (S33), the call processing processor to which the subscriber number belongs with the received subscriber number is found (S34). The user data processing function existing in the call processing processor ( UDHF) transmits a subscriber deletion request (S35). Upon receiving the subscriber deletion request (S36), the user data processing function (UDHF) detects whether the corresponding subscriber number exists in the subscriber information relation (S37) and determines whether the same subscriber exists (S38).

The human machine interface transfer function (HANDF) outputs the error result to the operator terminal (S14). . If the subscriber number exists, the subscriber number is transmitted to the number data control function (NDCF) (S39), and the number data control function (NDCF) receiving the subscriber number (S40) deletes the information related to the corresponding subscriber number from the number translation relation. (S41) and transmits the result to the user data processing function (UDHF) (S42).

Upon receiving the result (S43), the user data processing function (HANDF) determines whether the result is an error (S44), and if it is an error, transmits the error result to the human machine interface transfer function (HANDF) (S12) and receives the error result. The human machine interface transfer function HANDF outputs an error result to the operator terminal (S14).

If the result is not an error, delete the corresponding app information in the subscriber information relation (S45) and transmit the deleted result to the human machine interface transfer function (HANDF) (S46) and receive the subscriber deletion result (S47). The subscriber deletion result is output to the operator terminal to the delivery function HANDF (S48). Next, when the number data control function (NDCF) receives the subscriber change instruction processing request (S49), it finds the call processing processor to which the subscriber number belongs with the received subscriber number (S50) and user data existing in the call processing processor. The subscriber change request is transmitted to the processing function (UDHF) (S51). The user data processing function (UDHF) receiving the subscriber change request (S52) detects whether the corresponding subscriber number exists in the subscriber information relation (S53) and determines whether the same subscriber exists (S54). An error result indicating that a number does not exist is transmitted to the human machine interface transfer function HANDF (S12), and an error result is received (S13), and the human machine interface transfer function (HANDF) error result is output to the operator terminal (S14). If the subscriber number exists, if the interface module number and link number are changed, the subscriber number and the interface module number and link number are transmitted to the number data control function (NDCF) (S55).

A sixth step of outputting to the terminal (S14); and if the result is not an error, changing the subscriber information in the subscriber information relation (S61) and transmitting the changed result to the human machine interface transfer function (HANDF) (S62). And the human machine interface transfer function (HANDF) receiving the subscriber change result (S53) includes an eighth step of outputting the subscriber change result to the operator terminal (S64). How to manage your data. The method of claim 1, wherein the fourth process, when the NDCF receives a subscriber information output command processing request (S65), finds a call processing processor having the received subscriber number and to which the subscriber number belongs (S56). The first step of transmitting a subscriber information output request to the user data processing function (UDHF) existing in the call processing processor (S67), and the user data processing function (HANDF) The second step of searching for the existence of the corresponding subscriber number in the subscriber information relation (S69) and determining whether the subscriber number exists (S70), and the error result indicating that the requested subscriber number does not exist if it does not exist after the determination. The third step of transmitting to the interface transfer function (HANDF) (S12) and the human machine interface transfer function (HANDF) receiving the error result (S13) is an error determination. A fourth step of outputting the result to the operator terminal (S14), and if the subscriber number exists, searching for the corresponding subscriber information in the subscriber information relation (S71) and transmitting the searched result to the human machine interface transfer function (HANDF) ( S72) The fifth step and the human machine interface transfer function (HANDF) receiving the subscriber information output result (S73) include a sixth step of outputting the subscriber information output result to the operator terminal (S47). A method for managing subscription data of ATM VC exchange. The interface module as claimed in claim 1, wherein the fifth process is information received when a subscriber number output command processing request rule user interface processing function (UDHF) is received from the human machine interface transfer function (HANDF) (S75). The first step of searching for the subscriber information relation with the number and the link number (S76), and after the search, finds all the subscriber numbers belonging to the corresponding interface module number and the link number and sorts the subscriber numbers in ascending order (S77). The second step of transmitting the subscriber number output result to the human machine interface transfer function (HANDF) (S78), and the human machine interface transfer function (HANDF) receiving the subscriber number output result (S79) is to operate the subscriber number output result. The output seek to the terminal (S80) subscriber data management of the ATM VC switch, characterized in that comprises a ninth step Way.
